Dearomatization of 3-cyanoindoles by (3 + 2) cycloaddition: from batch to flow chemistry

synthesis of some new sugar based 3, 3-disubstituted monocyclic β-lactams by asymmetric [2+2] cycloaddition reactions

synthesis of some new monocyclic β-lactams containing a quaternary carbon center via a [2+2]cycloaddition reaction is described. the reaction of achiral diphenyl ketene with chiral aldimines derivedfrom chiral 2, 3, 4, 6-tetra-o-acetyl-β-d-galactopyranosylamine, 2, 3, 4, 6-tetra-o-acetyl-β-dglucopyranosylamine and different benzaldehydes resulted in the formation of β-lactams as singlediastereo...

A Theoretical Study on Cycloaddition of 2-Ethyny1-2, 3-Dihdrofurane and Phenyl Azide

A theoretical study of the kinetics and mechanism of second-order intermolecular C.) cloadd it ion of 2-Ethyny1-2,3-Dihydrofurane and Phenyl Azide was performed using DFT method at 101.111 le) cl of theory with 6-31 PrEG(d,p) basis set at 298.15K. Equilibrium molecular geometries and harmonic ) ihrational frequencies ofthe reactants, transition state, and product were calculated. The kinetic an...

GaCl3-assisted [2 + 3] cycloaddition: a route to tetrazaphospholes.

The GaCl3-assisted [2 + 3] cycloaddition of Mes*-N=P-Cl (Mes* = 2,4,6-tBu3C6H2) with trimethylsilylazide (TMS-N3) results in the formation of the first tetrazaphosphole, stabilized as a GaCl3 adduct in high yields (>96%).

Dearomatization reactions of N-heterocycles mediated by group 3 complexes.

Group 3 (Sc, Y, Lu, La) benzyl complexes supported by a ferrocene diamide ligand are reactive toward aromatic N-heterocycles by mediating their coupling and, in a few cases, the cleavage of their C-N bonds. When these complexes reacted with 2,2'-bipyridine or isoquinoline, they facilitated the alkyl migration of the benzyl ligand onto the pyridine ring, a process accompanied by the dearomatizat...
